I am in the middle of replacing a cracked thermostat housing and would like to put a new thermostat in while I have everything disasembled. I thought the thermostat would come out with the housing but it is stuck inside the block quite bad. I am reluctant to manhandle it out but that seems to be the only way to get it at this point. Is this common and is there an easy way to remove the thermostat that I'm missing? I attached an image so you all can see what I'm working with.
